It's not a flip-flop if you change your answers between EE profile and PR Application. You should not change anything after PR application is submitted.I don’t want to flip-flop between accompanying and non accompanying as I feel like it might be considered misrepresentation. And from @vensak’s latest response, it doesn’t sound like an option anyway.
Just out of curiosity, if my husband were to get GC initiated, would that be considered a valid reason? Though I’m not sure I’d proceed with EE at that point since I can work in the US.
US GC is completely separate. If you get US GC, then you cannot hold Canadian PR (US doesn't like it). Just applying for GC is fine though. Canada doesn't mind you keeping their PR as an option while apply for PR (GC) elsewhere. If both of you were born in India, getting US GC is pretty much going to take forever. You will see many people on this forum have obtained Canada PR because their US GC process is not going anywhere.
